Monday I made a kolsch with liquid yeast and I made a starter with it as well. After all was put into the fermenter, I did not see anything for a day and a half. Last night I checked on it and still nothing, but for some reason, an hour later I checked again, I saw the starting of the foam and bubbles. I was worried that something was wrong and wanted to know if I should pitch some more yeast or what. I have read a few posts of other people worried about their beer and reading "Just wait a few days..." so I took that advice. Today, there are even more bubbles, 2-3 within 15 seconds and more foam as well.
I have really learned a lot from these forums. Thank you everyone for your advice/information.
